The H+ is the correct answer.
An alpha particle is basically a He atom that has no electrons. Therefore it has a 2+ charge.
Alpha particle: 2 protons, 2 neutrons, 0 electrons = 2+
H+: 1 proton, 0 neutrons, 0 electrons = 1+
This is the only choice with a positive charge like the alpha particle.

an alpha particle is just a helium atom strip of all its electrons, therefore it has 0 electrons. ans A will have 2 electrons and so has B while D has 10 so onli C does not hav any cos H+ means a hydrogen atom (which onli has an electron) being strip of 1 electron........=)

Alpha particles are helium nucleus and contain no electrons. H+ is a proton and contain no electrons as well.
